TVU Networks Receiver/Transceiver devices running firmware before version 7.9 contain an authentication bypass vulnerability in the web management login endpoint POST /tvu/Login that allows remote unauthenticated attackers to obtain an administrative session by submitting an empty or absent UserName parameter.
